Firefox Support Forum

I updated to the latest version yesterday and now my Bookmarks ,History and a few other things have gone into Dark Mode. I really don't care for it and have tried looking into my settings but I see nothing that I can do to go back to the normal white. I am using Windows 11 on an HP All In One Desktop computer. Is there anything I can do to revert back to the way it was? Thanks for any reply.

I made a post the other week about issues I was having with Firefox & YouTube.

Having put the browser in safe mode I discovered that it was my ad blocker/s. That said, I had notice Firefox lagging or loading hard on video sites, not just YouTube as well as some applets on other sites. And having experimented with various ad blockers and video sites as well as my own blogs, I find that I am not having these problems with ad blockers in Chrome or Edge, but only Firefox, so much so, that most of these sites are entirely unusable unless I disable the ad blocker/s in Firefox.

Frankly, I've been noticing it for some time, but as of the other week they have nearly rendered the browser unusable, or the ad blocker/s unusable in Firefox on said sites. I have completely uninstalled and reinstalled the add-ons, from the Mozilla site, to no real avail.

It is not only annoying but very frustrating and I am about to give up, on the browser altogether. I am not having these problems with the same ad blocker/s in Chrome.

I've spent nearly two weeks on this and it hasn't gotten better.

There it is. Thank you.

Tried to reset settings. Does not work. Went to about:config, than tab.mo / print.tab_modal.enabled set to false. Did this method before and it worked. Now this method does not work trying to get print preview back. Firefox is my web browser. I am in windows 8.1. Seems like Firefox did some updates again and now I can not get print preview back! WHY DOES NOT FIREFOX LEAVE WILL ENOUGH ALONE WHEN THEY HAVE SOMETHING GOOD? Bring back the old classic print preview button back and leave it. Now how can I get the old print preview button back???? Need help!! Thanks philm

I just updated last night to version 98.0 of Firefox, and have noticed that when I click on manage bookmarks that the boomarks now open at the bottom of the various bookmarks folders by default instead of opening at the top like they used to. What happened here? I am including a picture to show where the manage bookmarks section is going by default now instead of where it normally does. Can anyone help fix this?

Firefox can no longer play Netflix movies. Firefox loads the Netflix site. Firefox attempts to play the movie. Then, Firefox can't play the movie. Netflix says "Your browser is no longer supported." This happens every time there is a Firefox update! Do you guys not test your products in development before release? Please fix your product. I tried all your 'help' items.

My Firefox browser seems to have reset itself to Windows 8 compatibility. I have Windows 10, 64-bit. Firefox will not open full screen, but opens a tiny, narrow window at the bottom of the screen which I have to use task manager to close. I remember one of the automatic updates coming through a few days ago.

Can I do anything other than uninstalling and a new install? I'd like to keep my favorites list, etc. I am at the extent of my computer skills with this.

FF will now not let me log into a site Ive used many times, Ive cleared the cache, remove data, Im not to much techno knowledge but have done that then gone to saved log ins and removed original log in that was saved, gon back to the (site which is my energy supplier) put in my email, then password all is correct but it just will not open anything the dots on top left of page just keep going back and forth, yet if i go onto IE and log in it comes up instantly, maybe I should change!!

I've noticed that with Firefox 102 when I download an exe file, in this case Thunderbird Setup 102.0.exe it is renaming it to Thunderbird Setup 102.0.exe.bin.

Why is that happening now? I know the "potential risk" or downloading an .exe file but shouldn't it ask or at least warn you instead of just deciding to rename it

I didn't see a setting to disable this "feature". Is there one?

Thanks

Hello there to anyone who can help me with this problem that I'm having right now. Yesterday while watching and going through the videos on youtube, while watching a video, it suddenly started to lag and not move as smoothly much as before when I have on a higher quality like in 1080p 60fps or 720p60fps.

This has happen to me a couple times before when I couldn't find a way to fix it like when my my laptop was acting stupid and was resetting itself and showing a blue screen when it happen and had someone help me take it to the store and have it fixed and the reset my laptop or something and had to go redownload Firefox and I think the problem stopped working.

Yesterday and today I tried searching and looking up how to fix this and find answers that tell me to go to the about:config and change somethings to false or true whatever and it still has this problem. I hope changing it to whatever doesn't mess it up anything even more.

I thought I had to go update Windows or something since recently a couple of times the youtube videos get stuttery and not move as smoothly at times. I can't remember much this one but I either just close Firefox to hopefully that it goes back to normal or I have to update Windows to restart my laptop and it works and it goes back to normal.

But this time when I did all that and I try to update Windows from my laptop it was doing what it does updating installing or downloading yesterday. The problem is still there and the videos on youtube are still stuttering. And I try to see if there were more things to update there was nothing there and says its up to date.

I linked a video that has a 60fps option on a another browser Microsoft Edge to see if it works from there and video when putting it on 60fps works fine there. So this must be a Firefox problem or something.

So if anyone can help me with this problem. Please tell if there's anything else I can do to get these videos on youtube to work on Firefox in 60fps and hopefully can try to easily fix this and hope its nothing complicated to do. Or if there is a bug or something that's making these videos stuttering and everything please try to fix this problem that's going with me right now. Cause i don't want to have to deal with problem I had before again forever and/or if its permanent.

Hopefully maybe the next update for Firefox might fix this problem I have from these youtube videos, but I don't know. Whenever an update for Firefox happens sometimes, the videos on youtube start to stutter and not move as smoothly with putting it on 60fps and have this problem again.

Thank you if anyone has the time to look at this and hopefully someone can get me the answer to finally fix these videos that are freezing stuttering and stuff there.

Hello. Firefox quickly takes up all the space on the SSD. After about two days of work, there is no disk space left. Closing the browser helps, but it's not comfortable. Windows 10 system.

I've been using Firefox since Netscape ended and i always enjoyed it. Unfortunately the Firefox 72 is utterly hideous. It is the worst and most unstable browser i ever tested -- it's extremely slow, it doesn't even work with hardware acceleration, it's not compatible with most sites i access and it crashes a lot. Anyway I already reinstalled the version 71, which continues to work flawless and I don't plan to ever use auto updates again. The problem is that every single day Firefox tries to update to the horrible 72 version, and every day I have reject it manually.

I'm looking for a way to permanently block future Firefox updates, without asking me for it again. Any ideas?

This command doesn't work, and I've seen others with the same issue and no one ever gave a response on how to fix it.

I'm assuming the same thing will happen here, but I just started using Fire Fox and really hope someone can give some resolve.

I tried running with no extensions too, it still didn't work.

Microsoft Edge Control + Shift + N works

Chrome Shift + N works

I tried this solution "Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is is causing the problem. " It didn't work.

Please could someone help me. Firefox has been my favorite go to browser, but now I am forced to look for alternatives.

I'd like to know why my previous question on this matter was deleted.

How do I change the font and line spacing characteristics?

Specifically, my tabs are now 4 pixels too high and the menu font spacing is also 4 pixels too high.

This has made the dropdowns for my bookmarks bigger than my screen (for example) and I find that I'm needing to move the mouse excessively from the extra space introduced when I right click on a page for menu options there as well.

Recently I’ve been receiving a 522 timeout error in Firefox attempting to reach URL www.cocoontech.com. The 522 is returned from Cloudflare’s reverse proxy servers (see uploaded image). However, I can successfully reach that URL using Chrome and MS Edge browsers. Only Firefox receives the 522 error. I can access numerous other websites with Firefox, so it seems to be isolated to just www.cocoontech.com. I’ve looked at numerous settings in Firefox, but have not seen anything that seems relevant to this issue.

Any ideas where to look to resolve this issue?

I updated my version from 88 to 89 but did not like so I went back to the 88 version. But I see I lost all the History Bookmarks and all tabs I had open. How can I get it back?

I tried to delete a couple of "add ons" that I didn't want by going into the Firefox directory, and clicking the specific ddl and hitting delete. Firefox no longer works and I did try to refresh to no avail. It did state that a report would be sent but I never heard back. Is my only option to uninstall and then reinstall?

Yes, i recall the last time i was asking for help with this issue i was told to post it as a bug somewhere. I went to "Feedback" thinking that was logical, but apparently Mozilla is reworking Feedback so that does not exist, and as i am not a software developer, i suspect a technical bug report is over my head anyway.

I don't want to go to Edge, but it would seem Mozilla wants me to. This issue has persisted ever since release 79. I would think that the programmer(s) could "simply" look at what changed from 78 to 79 and revert, but apparently not.

I, once again, have to uninstall the latest release (i installed it, allowing an "upgrade", thinking that by now someone there would have fixed that which at least to me is a critical routine), and reinstall Version 78.0, since that one isn't f'd up. Maybe it is all the enhanced "security" that is now interfering with normal processes, i don't know. That also means I have to get used to the new browser and hopefully finding a reliable password manager to which i can import pages of entries from Kee.

Yes, i know i will get a share of hate mail for criticizing FF at this point. Just consider how infuriating it is after using it since beta 0.3 and having made donations, having what i see as a critical issue ignored, and worse, forcing me to soon change to Edge if no one fixes it. As much as i hate using the Microsoft browser, at least it does not force the Microsoft "Save" dialog box to collapse when trying to print to a pdf, and i am rather disgusted that no one from FF has reached out to try to fix this issue.

And yes, i did try it in safe mode (run firefox.exe /safe) and "Restart with Addons disabled" from the menu|Help, neither of which were successful.

If any of you know how to get this note to someone competent at FF, please do so and let me know to hold off on switching; i dread having to do that, but printing to pdf is mission critical in the conduct of my business.

I don't like the new printer dialog box Firefox came up with. It is too basic. 9 times out of 10 I have to click over to the System Dialog Box. Is there any way I can permanently switch to System Dialog Box? I am running Windows 11/64
